lNCANDESCENT VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 663,120, dated December4, 1900.

Application filed April 5. 1900.

T0 ctl, whom t iva/(Ly concern:

Be it known that l, JOSEPH MELVIN DENS- MORE, acitizen of the UnitedStates, residing at Kansas City, in the county of Jackson and State ofMissouri, have invented certain new and usefulImprovementsinOil-Burners; and l do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to Which it appertains tol make and use the same.

My invention relates to incandescent-mantle-lamp burners for burninghydrocarbon oil; and it consists iu the construction and novelcombination of the parts of the same, as hereinafter fully described andclaimed.

The object of the invention is to provide a simple, durable, andeffective burner of this character which is not liable to get outoforder and in which provision is made to prevent clogging and to enablethe parts to be readily and conveniently attached and detached forcleaning and repairs or substitution of new parts. I attain this objectby the mechanical construction illustrated in the accompanying drawings,in which- Figure 1 is a vertical sectional view of the entire burner.Fig. 2 is a vertical sectional view of the burner with the valve and casing detached, showing the vaporizingchamber, the mixing-chamber, and thecombustion-chamber made in one piece of metal.

Referring by reference letters and numerals to the accompanyingdrawings, A designates the supporting-incasement, which is made integralWith and surrounds the mixing-chamber 6, which is located immediatelybelow and communicates with the combustion-chamber 11.

10 is a screen formed of wire of appropriate Viineness of mesh toretract the force of the gas and cause it to burn on said screen orpoint of ignition.

The oil-inlet pipe 1 is supplied with a filter 12, made of brass-wirescreen material of appropriate neness of mesh for filtering thehydrocarbon oil before Jentering the Vaporizing-chamber, and isexternally threaded on its inner end and engages athreaded seat 1a,having a vaporizing-chamber 1b, provided with passages 2 3, which aresubstantially Siphon-shaped, the vertically-depending lieg Serial No.11,702. (No model.)

3 communicating with the upper end of a downwardly and inwardly inclinedduct 4,

i leading to the small chamber Il at the lower end of said duct at, theupper end of said chamber #1a being provided with a needleseat 5 forreceiving the `point 5a of the needle 7 at the upper end of thevalveste1n`7. At the lower end the valve-stem 7 is provided with amilled nut for turning said stem 7 in its seat. 8 is a packing-burprovided interiorly with asbestos packing 8a to prevent leakage at thispoint. The needle-point 5 is for the purpose of cleaning the needle seator orifice 5to keep it open.

9 is a cylindrical incasement which is attached by friction to theburner at 13 13 and forms a housing around the burner to protect it fromsudden currents of air.

To light the lamp, heat is first applied to the interior of the burner,preferably using an alcohol-torch for said purpose. when turned on theoil enters at 1 and passing through filter l2 enters theVaporizingchamber 2 and following said chamber to 3, where it enters thechamber 4ta of the valvestem. During this How the oil has been convertedinto vapor and passes down and through the orifice 5 at theneedle-point, where it comes in contact with the oxygen of the air, thenpasses th rough the mixing-chamber 6 and to the screen 10, wherecombustion takes place in the combustion-chamber, forming the flame,which renders the mantle incandescent.

I am aware that prior to my invention carbon-oil incandescent-mantlelamps have been made with vaporiZing-chambers operating in conjunctionwith needle-valves. I do not claim such a construction, broadly, herein.

What I do claim as my invention, and desire to secure by Letters Patent,is-

A hydrocarbon-vapor burner, comprising in its construction an annularshell or incase* ment having a vertical mixing-chamber, acombustion-chamber located above the mixing-chamber, a seat or extensionformed on one side of the .incasementin line with the mixing-chamber andprovided with a vaporizing-chamber7 a hydrocarbon-supply pipe connectedwith the outer end of the seat or extension for supplying oil directlyto said Then l IOO vaporizing-chamber, a Siphon-passage in said seat orextension composed of npwardly'and diagonally and ve rtieally extendingbranches leading from the Vaporizing chamber in- Wardly to near the topof the mixing-chainber and thence downwardly and opening through thebase of the shell, a pendent pipe in communication with said passage andexy' tending diagonally to a point below the mixing-chamber and having avalve-controlled. discharge at its lower end, and an annularshieldinclosing the said pendent pipe and serving to receive the vaportherefrom and
